With a 6.5 mm (0.2559 inch) diameter and a six-flute straight configuration, it produces accurate, smooth bores to a tight tolerance of +0.0001 to +0.0005 inches. The bright, uncoated carbide construction provides rigidity and wear resistance across a range of workpiece materials. Overall length is 83 mm with a 29 mm flute length, making it suited for shallow to medium-depth reaming operations. It mounts via a straight cylindrical shank for use in standard drill chucks or collet holders on machining centers and lathes.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for production and job-shop environments where consistent bore diameter and surface finish are required. Its straight-flute geometry is well suited for reaming through-holes and short blind holes in ferrous and non-ferrous materials. The right-hand cutting direction and standard carbide grade make it a reliable choice for high-volume general machining. It is sold individually and is a direct fit wherever a 6.5 mm straight-shank chucking reamer is called out on a print.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6.5 mm (0.2559 inch) reamer diameter with +0.0001 to +0.0005 inch tolerance for precise bore finishing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eSix straight flutes for smooth cutting action and good chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose machining\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 83 mm OAL, 29 mm flute length — OSG Series 300D\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use chucking reamer for general machining applications requiring a 6.5 mm straight-shank reamer in any CNC or manual machine tool accepting a straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Secure the shank fully into a collet, drill chuck, or toolholder and verify runout before use. De-energize and lock out the machine spindle before changing tooling. Follow shop-standard speeds and feeds for carbide reamers; avoid running dry on materials that require cutting fluid.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 6.5 mm (0.2559 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 83 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 300D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 0.5 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300-2559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748423467314,"sku":"300-2559","price":78.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_d7f51f5b-e7a7-42e0-9a3b-9d36669e4f00.jpg?v=1788893617","url":"https:\/\/voomisupply.com\/products\/osg-300-2559-chucking-reamer-6-5mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
